I am working on a script that will walk a directory and change the source for a layer. This way when we move data I can just set this script to go update everyone's maps. In my own folder I can get it to run down to printing the layer source, I just can't get the replaceDataSource function to work. Any help? This is in 10.1
Also will I be able to replace a source to something that is loaded from a group or basemap layer?
Results when running the code:
>>>
Z:\Working\MXDs\BrkLyr_Map_2.mxd
Layer: Export_Output
Source: \Working\MXDs\Export_Output.shp
Traceback (most recent call last):
